1. Course Structure and Assessment | 课程结构与考核方式
The AQA Engineering GCSE is divided into two components: a written examination (Unit 1) and a non‑exam assessment (Unit 2). Together they test both theoretical understanding and practical application.
AQA 工程 GCSE 分为两个部分：书面考试（单元 1）和非考试评估（单元 2）。两者共同考查理论理解和实际应用能力。
The written paper lasts 1 hour 45 minutes and is worth 120 marks, contributing 60% of the final grade. The paper contains multiple‑choice, short‑answer, and extended‑response questions, and all topics from the specification can be assessed.
书面考试时长 1 小时 45 分钟，满分 120 分，占总成绩的 60%。试卷包含选择题、简答题和扩展回答题，考纲中所有主题都可能被考查。
The Non‑Exam Assessment (NEA) is a single design‑and‑make task, set by AQA in the autumn term of Year 11. It is marked by the teacher and moderated by AQA, contributing 40% of the final grade. Students produce a portfolio of evidence, including research, design development, CAD models, manufacturing plans, and a prototype.
非考试评估（NEA）是一项由 AQA 在 Year 11 秋季学期发布的单一设计制作任务。它由教师评分、AQA 审核，占总成绩的 40%。学生需要提交证据组合，包括调研、设计开发、CAD 模型、制造计划和原型作品。
2. Engineering Materials | 工程材料
Understanding materials is fundamental to all engineering disciplines. The specification groups materials into metals, polymers, ceramics, composites, and smart materials, each with distinct properties and working characteristics.
理解材料是所有工程学科的基础。考纲将材料分为金属、聚合物、陶瓷、复合材料和智能材料，每种都具有不同的特性和加工性能。
Ferrous metals like low‑carbon steel and cast iron contain iron and are generally magnetic. Non‑ferrous metals such as aluminium and copper do not contain iron and are often more corrosion‑resistant. Alloys, e.g. brass (copper and zinc) and stainless steel, are designed to enhance properties like strength or toughness.
黑色金属（如低碳钢和铸铁）含铁，通常具有磁性。有色金属（如铝和铜）不含铁，通常耐腐蚀性更好。合金（如黄铜和不锈钢）旨在增强强度或韧性等性能。
Polymers are divided into thermoplastics, which can be reheated and reshaped (e.g. acrylic, ABS), and thermosets, which cannot be remoulded once set (e.g. epoxy resin). Ceramics such as alumina and glass are hard, brittle, and resistant to high temperatures.
聚合物分为可重新加热成型的热塑性塑料（如亚克力、ABS）和成型后不可重塑的热固性塑料（如环氧树脂）。陶瓷如氧化铝和玻璃具有高硬度、脆性和耐高温的特点。
Composites combine two or more materials to achieve enhanced properties. Common examples include carbon‑fibre‑reinforced polymer (CFRP) and glass‑reinforced plastic (GRP). Smart materials respond to environmental changes; nitinol (shape‑memory alloy) returns to a preset shape when heated, and piezoelectric materials generate a voltage when stressed.
复合材料结合两种或以上材料以获得增强性能。常见例子包括碳纤维增强聚合物（CFRP）和玻璃纤维增强塑料（GRP）。智能材料能响应环境变化；镍钛诺（形状记忆合金）受热时恢复预设形状，压电材料受应力时产生电压。
3. Manufacturing Processes | 制造工艺
This area covers the techniques used to shape, join, and finish engineering products. Students need to know both traditional methods and computer‑controlled processes, linking each to specific materials and design requirements.
本部分涵盖用于成型、连接和精加工工程产品的技术。学生需要了解传统方法和计算机控制工艺，并将每种工艺与特定材料及设计要求联系起来。
Material removal processes include turning, milling, drilling, and grinding. On a centre lathe, the workpiece rotates while a cutting tool moves along its axis, producing cylindrical parts. Milling uses rotating cutters to remove material from a stationary workpiece.
材料去除工艺包括车削、铣削、钻孔和磨削。在中心车床上，工件旋转而刀具沿轴线移动，可加工圆柱形零件。铣削则利用旋转刀具从固定工件上去除材料。
Shaping processes without material removal are equally important. Casting pours molten metal into a mould; injection moulding forces molten polymer into a die under high pressure; and forging shapes metal through compressive forces. Press forming and bending are commonly used for sheet metal.
不涉及材料去除的成型工艺同样重要。铸造将熔融金属注入模具；注塑成型在高压下将熔融聚合物注入模具；锻造通过压缩力使金属成型。冲压和折弯常用于金属板材。
Joining techniques range from mechanical fasteners (bolts, rivets) to thermal processes (welding, soldering, brazing). Adhesive bonding and using knock‑down fittings are common in manufacturing with woods and plastics. Finishing operations such as painting, powder coating, and anodising protect surfaces and improve aesthetics.
连接技术包括机械紧固件（螺栓、铆钉）和热加工工艺（焊接、软钎焊、硬钎焊）。粘接和使用快拆配件在木材和塑料制造中很常见。精加工操作如喷漆、粉末涂层和阳极氧化可保护表面并改善外观。
4. Mechanical Systems | 机械系统
Mechanical systems transmit and transform forces and motion. The AQA specification expects students to calculate mechanical advantage, velocity ratio, and efficiency for simple machines, and to describe how levers, linkages, gears, and cams work.
机械系统传递和变换力与运动。AQA 考纲要求学生计算简单机械的机械增益、速度比和效率，并能描述杠杆、连杆、齿轮和凸轮的工作原理。
Levers are classified into three orders depending on the relative positions of the effort, load, and pivot. A first‑order lever has the pivot between effort and load (e.g. a crowbar); a second‑order lever has the load between pivot and effort (e.g. a wheelbarrow); a third‑order lever has the effort between pivot and load (e.g. tweezers).
杠杆根据施力点、负载与支点的相对位置分为三类。一级杠杆支点在施力点与负载之间（如撬棍）；二级杠杆负载在支点与施力点之间（如手推车）；三级杠杆施力点在支点与负载之间（如镊子）。
Gears change rotational speed, torque, and direction. A simple gear train ratio is found by dividing the number of teeth on the driven gear by the teeth on the driver. For a compound gear train, the intermediate gears alter both speed and torque. The velocity ratio (VR) of a pulley system equals the number of rope sections supporting the load.
齿轮改变转速、扭矩和方向。简单齿轮组的传动比等于从动轮齿数除以主动轮齿数。对于复合齿轮组，中间齿轮同时改变转速和扭矩。滑轮系统的速度比（VR）等于支撑负载的绳索段数。
Mechanical Advantage (MA) = Load / Effort
Velocity Ratio (VR) = Distance moved by effort / Distance moved by load
Efficiency = (MA / VR) × 100%
5. Electronic and Electrical Systems | 电子与电气系统
This section covers basic circuit theory, components, power supplies, and the use of microcontrollers. Engineers often integrate electronic control with mechanical systems, so understanding both is essential.
本部分涵盖基本电路理论、元器件、电源及微控制器的使用。工程师常常将电子控制与机械系统结合，因此理解两者至关重要。
Ohm’s law relates voltage (V), current (I), and resistance (R):
V = I × R
欧姆定律描述了电压（V）、电流（I）和电阻（R）之间的关系：
V = I × R
Students should recognise common input components such as LDRs (light‑dependent resistors), thermistors, and switches. Process devices include transistors, comparators, and integrated circuits like the 555 timer. Output devices range from LEDs and buzzers to motors and solenoids.
学生应识别常见输入元件，如光敏电阻（LDR）、热敏电阻和各种开关。处理元件包括晶体管、比较器和集成电路（如 555 定时器）。输出元件有发光二极管、蜂鸣器、电机和电磁铁等。
Microcontrollers (e.g. Arduino, PICAXE) allow programmable control. Flowcharts and pseudocode are used to design programs that read sensor inputs and drive outputs. Power supplies, including batteries and voltage regulators, must be selected to match the voltage and current requirements of the circuit.
微控制器（如 Arduino、PICAXE）可实现可编程控制。流程图和伪代码用于设计读取传感器输入并驱动输出的程序。电源包括电池和稳压器，必须根据电路的电压与电流需求进行选择。
6. Structural Systems | 结构系统
Structures must withstand forces without collapsing or deforming unacceptably. This topic introduces the concepts of tension, compression, bending, torsion, and shear, and explores how materials and shapes resist these forces.
结构必须承受各种力而不倒塌或发生过大的变形。本主题介绍拉伸、压缩、弯曲、扭转和剪切等概念，并探讨材料和形状如何抵抗这些力。
A simply supported beam under a central load experiences compression in the top fibres and tension in the bottom. Hollow tubes, I‑beams, and corrugated sheets are examples of structural forms that increase stiffness while minimising weight. Triangulation is used in frames to convert bending forces into tension and compression in members.
简支梁承受中点载荷时，上部纤维受压，下部纤维受拉。空心管、工字梁和波纹板是在减轻重量的同时增加刚度的结构形式实例。框架中采用三角结构可将弯曲力转化为构件的拉伸与压缩。
Students should be able to calculate the force in a structural member using moments: for a system in equilibrium, the sum of clockwise moments equals the sum of anticlockwise moments about any point: Σ Mcw = Σ Macw.
学生应能利用力矩计算结构构件中的力：对于平衡系统，绕任一点所有顺时针力矩之和等于逆时针力矩之和： Σ Mcw = Σ Macw。
7. Pneumatic Systems | 气动系统
Pneumatics uses compressed air to generate motion and force. It is widely used in manufacturing automation, particularly where clean, fast, and safe actuation is required.
气动系统利用压缩空气产生运动和力。它广泛应用于制造自动化领域，尤其适用于需要清洁、快速和安全驱动的场合。
A basic pneumatic circuit includes a compressor, an air receiver, a filter‑regulator‑lubricator (FRL) unit, valves, and actuators. Directional control valves (e.g. 3/2 valve, 5/2 valve) switch the airflow path to extend or retract a cylinder. Students must read and draw circuit diagrams using standard symbols.
基本气动回路包括压缩机、储气罐、过滤‑调压‑润滑（FRL）组件、阀和执行器。方向控制阀（如 3/2 阀、5/2 阀）切换气流路径以伸出或缩回气缸。学生须使用标准符号读写气动回路图。
tors produce linear (cylinders) or rotary (motors) motion. The force developed by a double‑ nds on the air pressure and the piston area: F = P × A. Sequencing circuits can use roller‑operated valves or electrical‑pneumatic control to automate repetitive tasks.
气动执行器产生直线运动（气缸）或旋转运动（马达）。双作用气缸产生的力取决于气压和活塞面积：F = P × A。顺序控制回路可利用滚轮操作阀或电气‑气动控制来实现重复任务的自动化。
8. Testing and Quality Control | 测试与质量控制
Engineers test materials and products to ensure they meet specifications and are safe for the intended use. This topic links to practical work in the NEA, where students must evaluate their own prototypes.
工程师对材料和产品进行测试，确保其符合规格并适合预期用途。本主题与 NEA 中的实践工作紧密相关，学生必须评估自己的原型。
Destructive tests include tensile testing (measuring UTS, yield strength, and elongation), hardness testing (using Rockwell or Vickers methods), and impact testing (Charpy or Izod tests). Non‑destructive tests such as visual inspection, dye penetrant, and ultrasonic testing are used to detect surface or internal flaws without damaging the part.
破坏性测试包括拉伸试验（测量抗拉强度、屈服强度和延伸率）、硬度试验（使用洛氏或维氏方法）和冲击试验（夏比或艾氏冲击试验）。非破坏性测试如目视检查、着色渗透和超声波检测可在不损坏零件的情况下检测表面或内部缺陷。
Quality assurance covers all planned activities that build quality into a product, while quality control refers to the inspection and measurement of outputs. Statistical process control (SPC) and tolerance tables are used to monitor consistency during production.
质量保证涵盖所有将质量植入产品中的有计划活动，而质量控制指的是对产出进行检验和测量。统计过程控制（SPC）和公差表用于监控生产过程中的一致性。
9. Modern Technologies in Engineering | 工程中的现代技术
Engineering is constantly evolving through digitisation and automation. The specification requires learners to understand how CAD, CAM, 3D printing, and robotics affect design and manufacture, as well as to consider the environmental and ethical dimensions.
工程通过数字化和自动化不断演进。考纲要求学生了解 CAD、CAM、3D 打印和机器人技术如何影响设计与制造，并思考相关的环境和伦理议题。
Computer‑aided design (CAD) software produces 2D and 3D models, allowing virtual testing and photorealistic rendering. Computer‑aided manufacture (CAM) translates these models into machine instructions (G‑code). Additive manufacturing (3D printing) builds parts layer by layer, which reduces waste in prototyping and low‑volume production.
计算机辅助设计（CAD）软件可生成二维和三维模型，支持虚拟测试和逼真渲染。计算机辅助制造（CAM）将这些模型转换成机器指令（G 代码）。增材制造（3D 打印）逐层构建零件，减少了原型制作和小批量生产中的浪费。
Sustainability principles such as the 6Rs (reduce, reuse, recycle, repair, refuse, rethink) are integral to modern engineering. Life cycle assessment (LCA) evaluates the environmental impact from raw material extraction through to disposal. Renewable energy systems and lightweight design help lower a product’s carbon footprint.
现代工程不可或缺的可持续发展原则包括 6R（减量、重用、回收、修复、拒绝、再思考）。生命周期评估（LCA）评价从原材料提取到废弃处理整个过程的环境影响。可再生能源系统和轻量化设计有助于降低产品的碳足迹。
10. Non‑Exam Assessment (NEA) Breakdown | 非考试评估（NEA）详解
The NEA is a substantial project where students identify a design need, generate ideas, develop a solution, manufacture a prototype, and evaluate its performance. The mark scheme awards marks for each stage of the engineering design process.
